My low mile all original ls6's fuel pump has the return line.I believe early ls6's did not have the return line.My car is a june car.

I saw a July LS-6 car that had a return line as well. I just assumed it was an LS-5 car. Is this change documented?

DSYenko,The part number could be 1 of 2.73-75 Chevelle 454 4" from bottom to mtg holes #6472381.73 Chevelle 454 4.5" from bottom to mtg holes #7470761.These are OE applications so anything is possible.Hope this helps.

DS: ours is the stock 396/427 AC replacement, available from our sponsor above (D&R Classic Automotive)...not near as fancy as what a lot of the guys are running, but it carries our fat @ssed Camaro through the traps at 113+...

I believe this would be it, but when you call, make sure this is for the solid lifter big blocks (read: Holley cars):

Hate to drag this on and on but this pump does not have the return line correct??

I looked again, and I'm not sure that's the right link...call 'em up, and tell 'em you want the pump for a '69 L78, which will NOT have a return...they also list a repro pump for a ZL1, and have a picture of it, so you could go that route if you wanted...
